Metaethical relativism is the idea that moral truths are relative to a particular culture or society. This means that what is considered to be morally right or wrong may vary depending on the cultural or societal context. Metaethical relativism is concerned with the nature of morality itself and whether moral truths are objective or subjective.
Normative relativism, on the other hand, is the idea that moral judgments are relative to the individual or group making the judgment. This means that what is considered to be morally right or wrong may vary depending on the individual or group's perspective. Normative relativism is concerned with how we should make moral judgments and whether there are any universal moral principles that apply to all people.
In summary, metaethical relativism is concerned with the nature of morality itself, while normative relativism is concerned with how we should make moral judgments.
